    Intel Centrino Wireless-N 1000

    Hello everyone, I recently installed Ubuntu 12.04 and Windows 7 (dual boot) on my HP laptop. But the wireless network is not working on Ubuntu 12.04. I can see all the available wireless networks but I'm unable to connect.

    Code :
    lspci | grep Network

    02:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 [Condor Peak]


    Code : iwconfig

    Man, oh man! You have a lot of wireless drivers loaded! I suspect most of them are wrong and that they conflict. Please show me:
    Code:
    lspci -nn | grep -e 0200 -e 0280
    cat /etc/modules
    lsmod
    Thanks.

    Re: Intel Centrino Wireless-N 1000

    I am quite confident that the conflicting Broadcom drivers are not helping here. Let's fix things up a bit:
    Code:
    gksudo gedit /etc/modules
    Remove the brcmsmac line, proofread carefully, save and close gedit. Next do:
    Code:
    sudo apt-get remove --purge bcmwl-kernel-source
    After it is finished, reboot and let me hear your report.

    Re: Intel Centrino Wireless-N 1000

    I removed the brcmsmac line and bcmwl-kernel-source and reboot my computer, but it couldn't solve my problem. It tries to connect to the wireless network and prompt "wireless network disconnected" message

    Now please do:
    Code:
    sudo -i
    echo "options iwlwifi 11n_disable=1"  >>  /etc/modprobe.d/iwlwifi.conf
    exit
    Reboot and let me have your report. If it is not connecting, please post:
    Code:
    lsmod
    dmesg | grep iwl
    Thanks.

    @ yonasbel,

    You should post the command outputs within 'Code' tags to preserve their formatting and make the post compact and more readable. To see a quick 'HowTo' with screenshots, follow the "Using Code Tags" link in my signature. I'm sure you'd like it, as we do.

    Ah, haaa!! Let's try updating the firmware. With a working wired ethernet connection, please do:
    Code:
    sudo apt-get install --reinstall linux-firmware
    Reboot and do:
    Code:
    dmesg | grep iwl
    Is the same message still there? If so, let's try this. Download this file to your desktop. http://wireless.kernel.org/en/users/...-39.31.5.1.tgz Right-click it and select 'Extract Here.' Now open the terminal and do:
    Code:
    cd Desktop/iwlwifi-ucode-39.31.5.1
    sudo cp iwlwifi-1000-5.ucode  /lib/firmware/
    Reboot and see if it is now working.

    Notice, for the benefit of the searchers and driver dawgs out there, that dmesg said, "...expected v5, got v3." We are installing iwlwifi-1000-5.ucode.
